Docs Remove SVN ID, minor updates

- avp aliases support: any module can register and avp_galias (global alias) which will be visible for all other modules. Aliases should be exported as soon as possible, in modparam (by using function callbacks for processing the params) so that other modules will see them both in mod_init and fixup functions. In config scripts all aliases should start with "$".

- sock_lists completely re-organized

- aliases proto support

- added body_lumps (jan patches + some changes) - anchor_lump & del_lump compare the offset with msg->eoh and add the lump to add_rm or body_lumps, so make sure to parse_headers(HDR_EOH) if you lumps might modify the body. - changed all the {anchor,del}_lump calls
